Matching the part number or confirming with our parts team ensures you get the correct component.

How do I know which undercarriage size fits my Case dozer?

Undercarriage fitment depends on your machine serial number and the undercarriage size, since components differ across Case dozer generations. Match the part number on your existing component when possible, or confirm the correct size with our parts team. You can reach them at (800) 909-7060 for help identifying the right part.

What are the signs my Case dozer sprockets or rollers need replacing?

Worn sprockets often show pointed or hooked teeth, and worn rollers and idlers can cause track slap, uneven wear, or reduced traction. When ground-engaging undercarriage parts wear out, crawler travel and traction suffer. Broken Tractor carries replacement rollers, idlers, sprockets, track chains, and shoes to restore proper track performance.
